CROSS-REFERENCE TO RELATED APPLICATION

[0001] This application claims the benefit under 35 U.S.C. § 1.119(e) of Provisional Application Serial No. 60/268,825 filed Feb. 14, 2001, the disclosure of which is incorporated by reference in its entirety herein.

FIELD OF THE INVENTION

[0002] This invention relates to compositions of biochemical compounds involved in bioenergy metabolism of living cells and methods of use in the prevention and therapy of diseases in humans.

BACKGROUND OF THE INVENTION

[0003] The fact that many human diseases develop at the level of cells is well established. Rudolph Virchow's “Cellular Pathology” (Virchow Rudolph, Cellular Pathology, Berlin, 1858) has become a leading principle of pathology. While the localization of the initiation of these diseases—the cell—was thereby defined, the variety of mechanisms that cause a cell to malfunction have remained insufficiently understood.

[0004] One of these pathological mechanisms that have remained obscure is a deficiency or a lack of bioenergy in the cell. Under physiological conditions the bioenergy of a cell is provided from sugar, proteins and fats that is catabolyzed in the cell. The common pathways of catabolism of food and for the generation of bioenergy in form of ATP are the Tricarboxylic Acid Cycle or Citric Acid Cycle (Krebs cycle) and subsequent cellular energy pathway, the cellular Respiratory Chain (respiratory chain) as well as the closely connected Urea Cycle (urea cycle).

[0005] The possibility of a deficiency of one or more of the Krebs cycle, respiratory chain and the urea cycle compounds are further enhanced by the fact that these biochemical pathways involve a multitude of enzymatic steps. Just recently the first molecular diseases involving an enzyme deficiency of the Krebs cycle have been characterized (Bourgeron T., et al., J. Clin. Invest. 93:2514, 1994; Rustin et al., Biochim Biophys Acta 1361:185,1997; Patel, M. S. and Harris R. A. FASEB J 9:1164,1995; Shoffner, J. M. and Wallace D. C. in C. R. Scriver et al. (Eds.) The Metabolic and Molecular Bases of Inherited Disease, 7th ed. New York: McGraw-Hill, 1995, p. 1535). Genetic disorders for one or more of these enzymes and/or one or more of the coenzymes involved inevitably lead to a deficiency of one or more of the biochemical compounds of these pathways.

[0006] Recently, several coenzymes (e.g. thiamine, nicotinic acid, ascorbic acid, riboflavin, Mg⁺⁺) of the Krebs cycle have been used in the prevention and adjunct treatment of certain health conditions (Beyond deficiency, 2nd Symposium of the New York Academy of Sciences on Vitamins, New York 1992; E. Ziegler, L. J. Filer (eds.) Present Knowledge in Nutrition 7th edition. ILSI Press, Washington D.C. 1996; Matthias Rath, Alexandra Niedzwiecki. J Appl. Nutrition 48: 68-78, 1996). However, the biochemical compounds of the Krebs cycle itself, the respiratory chain and the closely connected urea cycle have not similarly been used.

[0007] Therefore there is a need for methods and compositions to prevent and treat malfunctioning of bioenergy metabolism of cells.

DETAILED DESCRIPTION OF THE INVENTION

[0019] Life is not possible without sufficient bioenergy being created at the cellular level. In a series of metabolic pathway proteins, carbohydrates and fats are converted to adenosine triphosphate (ATP). Optimum availability of cellular energy is a precondition for health. Under normal conditions, e.g. in a young and healthy individual, the cells of the body create an optimum amount of cellular energy to maintain the diversified functions of the body.

[0020] With advanced age and under pathological conditions, the cells of the body are frequently not able to provide sufficient energy to maintain physiological functions of the body, despite optimum intake of food. Moreover, several inherited disorders have been identified in which enzymes of the cellular energy metabolism are affected, leading to neurological disorders and other clinical manifestations.

[0021] The common catabolism of food and the generation of bioenergy relate to the Krebs cycle, the cellular respiratory chain as well as the closely connected urea cycle. The basic biochemical compounds of the biochemical pathways have been elucidated. FIG. 1 summarizes the biochemical pathways of Krebs cycle. FIG. 2 summarizes the biochemical pathways of respiratory chain. FIG. 3 summarizes the biochemical pathways of urea cycle. While the biochemical structure of these compounds is known, they are currently not used in medicine as preventive and therapeutic agents.

[0022] a) The Krebs Cycle

[0023] The biochemical intermediates of the Krebs cycle claimed in this patent are: citrate, cis-aconitate, isocitrate, oxalsuccinate, α-Ketoglutarate, succinyl-coenzymA, succinate, fumarate, malate, oxalacetate as well as the biochemical compounds that are immediate precursors of the Krebs cycle, namely acetyl-coenzyme A and pyruvate.

[0024] Due to the varying importance of these compounds for energy metabolism, they were divided into two categories for the purposes of this invention:

[0025] A. Category A (Table 1): succinate, fumarate, L-malate, α-ketoglutarate.

[0026] B. Category B (Table 2): citrate, cis-aconitate, isocitrate, oxalsuccinate, succinyl-coenzyme A, oxalacetate as well as acetyl-coenzyme A and pyruvate.

[0027] Genetic defects affecting the Krebs cycle and other metabolic energy cycles of cells have been reported. Neuromuscular disorders may have underlying mitochondrial metabolic defects: reduction of mitochondrial malic enzyme activity (Stumpf et al. Friedreich attaxia: III. Mitochondrial Malic Enzym Deficiency, Neurology 1982; 32: 221-7). Fumarase deficiency patients have severe neurological impairment (e.g., progressive encephalopathy). Fumarase deficiency is an autosomal recessive enzephalopathy affecting both the mitochondrial and the cytosolic enzymes (Walker et al., Journal of Inherited Metabolism Disorder 12 (1989), 331-332; Gellera et al., Neurology 1990, 40 (3 Pt 1): 495-9; Bourgeron et al., Journal of Clinical Investigations 1994 June; 93 (6): 2514-8; Narajanan et al., Journal of Children Neurologie 1996 May; 11 (3): 252 -55; Coughlin et al., Mol. Genet. Meta. 1998 April; 254 -62).

[0028] Drugge et al. reported hereditary myopathy with legtic archdiocese, succinate dehydrogenase and aconitase deficiency (J. Med. Genet. 1995 May; 32 (5): 344-7). Dunkelman et al. reported 2 ketogluterate dehydrogenase deficiency with intermittents to ketoglutaric aceturia (Neuropediatric 2000 February; 31 (1): 35-8).). Thus, aconitase deficiency, 2-ketogluterate dehydrogenase deficiency and succinate dehydrogenase deficiency may be responsible for neurodegenerative diseases.

[0029] Current methodologies are lacking in finding means and methods to repair inherited and acquired mutations of genes encoding for enzymes essential for the compensation of deficiencies in the Krebs cycle and other metabolic energy cycles. Gene therapy remains widely theoretical. For example, repair of defective fumarase gene is still in experimental stage and it is still years from being applied in medicine. Moreover, gene therapy is associated with severe side-effects and high costs. There is so far no description of any composition of biochemical compounds nor their therapeutic use in the literature.

[0030] The present invention provides a method and composition for compensating such deficiencies in bioenergy metabolism by administering such lacking biochemical components to the body. The daily intake of the metabolic compounds of the Krebs cycle is further enhanced by the addition of ascorbate, thiamine, riboflavin, certain minerals and trace elements and other cofactors for the enzymatic reaction in this cycle. Optimum supply of these coenzymes can compensate—at least in part—for the insufficient availability of the enzyme itself due to a genetic defect, e.g., fumarase deficiency.

[0031] The present invention also provides the addition of NAD, NADH, FAD, FADH, NAPD, NAPD and other well known carrier of cellular energy has a synergistic effect to compensate for enzymatic defects of the Krebs cycle.

[0032] In a preferred embodiment, the present invention provides a composition comprising succinate, fumarate, L-malate, and α-ketoglutarate.

[0033] Preferably, the present invention relates to biochemical substances of the Krebs cycle are claimed as shown in Table 1, category A. TABLE 1 Krebs Cycle Compounds Category A Biochemical Substances Units Amount claimed Succinate Mg 0.01-100 Fumarate Mg 0.01-100 L-Malate Mg 0.01-100 α-Ketoglutarate Mg 0.01-100

[0034] In another preferred embodiment, the present invention provides a composition comprising citrate, cis-aconitate, isocitrate, oxalsuccinate, succinyl-coenzyme A, oxalacetate as well as acetyl-coenzyme A and pyruvate.

[0035] Preferably, the present invention relates to biochemical substances of other intermediate steps of the Krebs cycle as shown in Table 2, category B. TABLE 2 Krebs Cycle Compounds Category B Biochemical Substances Units Amount claimed Pyruvate Mg 0.01-100 Acetyl-Coenzyme A Mg 0.01-100 Citrate Mg 0.01-200 Cis-Aconitate Mg 0.01-100 Isocitrate Mg 0.01-100 Oxalsuccinate Mg 0.01-100 2-Oxo-Glutarate Mg 0.01-100 Succinyl-CoenzymA Mg 0.01-100 Oxaloacetate Mg 0.01-100

[0036] The bioenergy metabolic pathway, particularly the Krebs cycle, has been discovered a long time ago. Bioenergy metabolic pathway is very complex and is believed to take place in mostly closed systems. In skeletal muscle, the Krebs cycle functions as a closed cycle. It provides reducing equivalents to the electron-transport chain for ATP-synthesis and further provides essentially complete oxidation. In the liver, the Krebs cycle functions as an opened cycle. It allows carbon skeletons to enter and to leave the cycle at different sides and provides substrates for biosynthetic processes in the mitochondria and cytosol (Zinn et al., Fumerase Deficiency: The new cause of mitochondrial enzephallomyopathy, the New England Journal of Medicine, Volume 315, Aug. 21, 1986).

[0037] Although such deficiencies have been discovered many years ago, there seems to be a prejudice to administer compounds to compensate such deficiencies due to the described fact that such cycles are closed or allow only entrances of limited chemical compositions like carbon skeletons.

[0038] The present invention provides a specific composition of biochemical compounds that compensate enzyme deficiencies in the Krebs cycles in inherited or acquired defects. Without bound by any theory, the present invention discloses compositions of biochemical compounds that may compensate enzyme/intermediate deficiencies regardless whether Krebs cycle exists in closed or opened systems.
